This is a simple circuit using a
<a href="http://en.wikipedia.org/wiki/Transmission_line">transmission
line</a>.  The wave goes across the transmission line and is reflected
at the other end, because the line is not terminated properly.  This
creates a <a href="http://en.wikipedia.org/wiki/Standing_wave">standing
wave</a> on the line, which is a wave that oscillates but does not appear to
travel.  It is actually the combination of two waves (the initial wave,
and the reflected wave) traveling in opposite directions.
<p>
In the
scope, you can see that the peak voltage across the resistor doubles
as soon as the wave is reflected, 4 nanoseconds after the oscillation
starts.  Click the <b>Reset</b> button to see it again.
